Abstract: Multi-phase permanent-magnet (PM) motor is a competitive candidate for application where uninterrupted operation is demanded under fault condition. However, double-phase open-circuit or short-circuit faults result in serious problems, such as high fluctuating-torque, deteriorated dynamic performance, even breakdown. This paper proposes a novel unified decoupling vector control strategy to restrain torque fluctuations and improve dynamic performance for a five-phase PM motor with arbitrary double-phase failures… Show more

“…In addition to preventing pulsating torque, this approach also provides fast dynamic performance. A few years later, the method from [257] was extended for double-phase faults in [255]. A difficulty for implementing these proposals is that measuring the current within the shorted phase windings is not straightforward [256].…”

“…A difficulty for implementing these proposals is that measuring the current within the shorted phase windings is not straightforward [256]. Moreover, although these techniques [255,257] are effective and fast, the FF compensation may not completely cancel the disturbance in case of significant uncertainties, such as machine and converter non-idealities. For this purpose, it may be possible to simply combine the fast dynamic response of the proposed FF compensation with additional control poles in the α 1 -β 1 plane for ensuring complete steady-state disturbance cancellation.…”

“…As to the multiphase motor drives, the asymmetric radial magnetic force can be eliminated by choosing proper winding arrangement. Besides, they offer higher fault-tolerant ability when compared with three phase motor drives [1], [2]. Moreover, permanent magnet synchronous motors (PMSMs) are widely used in industrial application for their high-power density, which makes multiphase PMSM a good choice for safety-critical applications [3], [4].…”
